Un De Sceaux falls as Flemenstar grabs the glory at Leopardstown

Andrew Lynch and Flemenstar clear the last on the way to victory at Leopardstown

Un De Sceaux’s dramatic exit two fences from the finish allowed Flemenstar to return to winning ways in the Paddy Power “So Quick, So Easy iPhone App” Chase at Leopardstown.

Willie Mullins' Arkle hero Un De Sceaux was all the rage having won each of his four starts over fences since falling on his chasing debut at Thurles and the front-running 1-4 favourite was still in command when hitting the second-last hard and coming to grief.

Both the horse and Ruby Walsh were quickly on their feet.

That left Flemenstar and British raider Simply Ned clear of the remainder and the latter looked likely to prevail when kicking clear from the home turn.

However, the Nicky Richards-trained eight-year-old began to tread water after the final fence and Andrew Lynch galvanised Flemenstar to get up and score by a length.

Now trained by owner Stephen Curran's son, Anthony, it was 16-1 shot Flemenstar's first victory in over two years and his first at Grade One level since his brilliant display in the 2012 John Durkan Memorial Punchestown Chase.

Later, Long Dog led from start to finish to claim the Paddy Power Future Champions Novice Hurdle.

The Willie Mullins-trained four-year-old was bidding for his sixth straight victory and his second at Grade One level, having seen off stablemate Bachasson in the Royal Bond at Fairyhouse last month.

The two stablemates locked horns once more, with Long Dog narrowly leading Bachasson for much of the two-mile journey, before the latter began to falter from the home turn.

Gordon Elliott's Tombstone and another Mullins inmate in Petit Mouchoir emerged as the biggest threats on the run to the final flight, but 9-4 favourite Long Dog dug deep to prevail by three-quarters of a length.

Tombstone was the same distance in front of Petit Mouchoir at the line.

Winning owner Rich Ricci said: "He's very brave and he clearly wants further – Ruby (Walsh) said he was flat-out the whole way.

"The ground was a bit too heavy for him, but he won that very well.

"He'll definitely go up in trip, but I'm not sure whether he'll run between now and Cheltenham – he seems to take his races very well.
